TL;DR: In this paper, various morphologies of Co-containing precursors such as nanorods, nanosheets, and nanocubes were prepared by controlling the solvothermal reaction using cobalt acetate, L(+)-lysine, and oxalic acid, all of which were successfully converted into Co 3 O 4 nanostructures without morphological variation.
Abstract: Various morphologies of Co-containing precursors such as nanorods, nanosheets, and nanocubes were prepared by controlling the solvothermal reaction using cobalt acetate, L(+)-lysine, and oxalic acid, all of which were successfully converted into Co 3 O 4 nanostructures without morphological variation. The gas responses of these Co 3 O 4 nanosheets, nanorods, and nanocubes to 100 ppm C 2 H 5 OH at 300 °C were 10.5, 4.7, and 4.5 times higher than those of the Co 3 O 4 agglomerated nanopowders, respectively. In addition, the selectivity to C 2 H 5 OH over CO and H 2 , as well as the response/recovery kinetics, were significantly improved. These enhanced gas-sensing characteristics were attributed to the less agglomerated nanostructures of the sensing materials.

TL;DR: In this article, the electrochemical oxidation of oxalic acid (OA) has been studied, in acidic media, at Ti/PbO2, highly boron-doped diamond (BDD), Pt, Au and Ti/IrO2-Ta2O5 electrodes, by both cyclic voltammetry and bulk electrolysis.

TL;DR: The porosity of anodic films formed in four major electrolytes, which was measured by pore-filling technique, decreases with increasing voltage as mentioned in this paper, however, at the voltages lower than 5 V the pore diameter increases while the cell diameter decreases.
Abstract: The porosity of anodic films formed in four major electrolytes, which was measured by pore-filling technique, decreases with increasing voltage Comparing the porosity at an identical voltage, it increases in the order of the films formed in sulfuric acid, oxalic acid, chromic acid, and phosphoric acid solutions When the voltage decreases down to lower than 10 V, the porosity increases remarkably, especially in the films formed in phosphoric acid The pore diameter estimated from the porosity and cell diameter measured by pore-filling technique decreases with decreasing voltage down to 5 V However, at the voltages lower than 5 V, the pore diameter increases while the cell diameter decreases Pore and cell diameters of the films formed in the four electrolytes at an identical voltage increase in the order: sulfuric acid, oxalic acid, chromic acid, and phosphoric acid These results are basically consistent with those reported in our previous TEM study, although the pore sizes are slightly larger than the latter's The reason of the discrepancy between the methods is discussed

TL;DR: In this paper, the half life for photolysis of oxalic acid and α-keto acids catalysed by iron(III) was shown to be in the order of a few minutes whenever the concentration of dissolved iron (III) is comparable to that of the organic acids.
